Material Optical materials such as quartz, glass ceramics, borosilicate glass, CaF2, MgF2, germanium, filter glass and other special materials are used. Specifications Flatness: Up to Lambda/30 PV measured at 632.8 nm depending on the critical area in reflection and wavefront depending also on material. Evaluation: According to ISO 10110, Part 5 or DIN 3140, Part 5 Surface defects: ISO 10110, Part 7 or DIN 3140, Part 7 up to 5/1 x 0.001 depending on the critical area Micro-roughness: Ra up to 0.3 nm depending on the material Quality Assurance In addition to permanent process and production control there is a very careful final inspection for which sophisticated measuring devices are available. Notes We manufacture monolithical optics (integration of more than one optical function in one glass component) as well as multifunctional optics (integration of mechanical functions in a glass component). Measuring Instruments for Quality Assurance Wavefront: Interferometer 4-24”, Shack-Hartmann-Wavefront-Sensor (UV and DUV) Resolution: Computer-supported MTF measurement Centering: Objective metrology station, Laser centering station Angle Precision: Goniometer, interferometer Transmission/ Reflection: Spectrometer, diode array Surface defects: Automatic microscope Micro-Roughness: White light interferometer, AFM Dimension: 3D Coordinate-measurement, caliper, CCD-Micrometer, Stitching interferometer
